SPECIFICATION forming part of Letters Patent No. 462,522, dated November 3, 1891.

Application led April l1, 1891. Serial No. 388,491, (No model.)

To @ZZ whom it may concern:

Be it known that we, JOHN L. ALEXANDER and WILLIAM E. ALEXANDER, both of Hazlegg, in the county of Boone and State ot' Indiana, have invented a new and Improved Boiler-Cleaner, of which the following is a full, clear, and exact description.

The object of the invention is to provide a new and improved boiler-cleaner which is siinple and durable in construction, very effective in operation, and arranged to draw oit all the impurities settling along the bottom of the boiler.

The invention consists of a pipe fitted to slide into the boiler through a blowot`f valve held on the boiler.

The invention also consists of certain parts and details and combinations ofthe same, as will be hereinafter fully described, and then pointed out in the claims.

Reference is to be had to the accom panyin g drawings, forming a part of this specification, in which similar letters of reference indicate corresponding parts in all the iigures.

Figure l is a plan view of the improvement as applied. Fig. 2 is a sectional side elevan tion ot the saine, and Fig. 3 is an enlarged transverse section ot the same on the line :ic at of Fig. 2.

The boiler A, on which the improvement is applied, is provided near its bottom and at one end with a blow-oft valve I3, the valve C of which is preferably in the shape of a gate, asis plainly illustrated in the drawings. From the outlet of the valve B extends a pipe D, carrying at its outer end a stuffing-box E, through which and the pipe D passes a pipe F, adapted to pass through the valve B when the gate C is drawn into an outermost position, as is plainly7 illustrated in Figs. 2 and The pipe F iits snugly into the pipe D as well as the valve B, all leakage being prevented by the stufiing-box E. The outer end ot the pipe F is provided with a suitable valve G, the valve-body of which is engaged by a rope II, the ends of which are fastened to and adapted to be wound upon a d ru in I, arranged transversely and mounted to turn in suitable bearings formed in a frame J, adapted to be clipped to the pipe D, as is plainly illustrated in Fig. On one outer end of the drinn I is secured a crank-arm K for convenient-l y turning the said drum I to wind up the ends of the rope H, so that a pull is exerted on the valve G to move the pipe F inwardly through the valve B along the bottom of the boiler.

The operation is as follows: Then the device is in the ordinaryT position, the pipe F is disconnected from the valve B and the latter is closed by its gate-valve C. Now when it is desired to clean the boiler the pipe F is in serted into the pipe D, the rope H is passed around the valve G, and the frame J, carrying the drum I, is clipped or otherwise secured on the pipe D. The valve G is held closed, and then the gatevalve C is drawn outward, so that the interior of the boiler is connected with the pipe F. The operator now turnsthe crank-arm K so that the pipe F is caused to slide inward through the valve B into the interior of the boiler. The inner end of the pipe F comes in contact with the impurities collecting in the bottoni of the boiler, the said impurities being instantly drawn oit by the operator opening the valve G. By further turning ot' the crank K the pipe F is slowly drawn into the boiler, so that all the impurities in the bottom of the boiler are disturbed by the inwardly-moving pipe, the impurities flowing into the said pipe and out of the same past the valve G. The pipe F is of sufiieient length so as to pass throughout the length of the boiler, whereby all the impurities in the bottoni of the boiler are drawn from the lattei. Then this has been accomplished, the valve G is closed, the pipe F is pulled outward, and when the inner end of the pipe F has passed the valve B then the gate C is again closed. The pipe F can then be readily taken ott the valve B and stored away until the device is again required for another cleaning of the boiler.

Having thus t'ully described oui' invention, we claim as new and desire to secure by Letters Patentl. The combination, with a boiler provided with a valve, ot. a \f'alve'pipe attaeliably secured to and iitted to slide through the valve into the boiler, substantially as and for the purpose set forth.

2. In a boiler-cleaner, the combination, with a blow-off valve attached to the boiler, of a IOD VIS

pipe fitted lto slide through the `said- .blow-,offv

valve, a Valve held on the outer end of the said pipe, and means, substantially' as de-y scribed, for forcing the said pipe through the said blow-olf Valve into the boiler, isubstantially as shown and described. v

4. A boiler-cleaner ,Constructed and arranged to be detached from the boiler when i not in use, whereby provision is made for preserving a smooth surface on the movable pipe tially as described, for mov-ing the ,Said xdis- A :boilercleaner eoniprising a Vb loW-.oif X Valveheld ,on the boiler, a kpipe 't-ted to slide in the said lblow-oft ,valve and provided with of thecleaner, substantially as described.

a valve, a rope adapted to be ,connected ,with

the body vof the .pipe-valve, and a ,drum held y on the said blowoff valve `and adapted ,towind 11p y o r unwind the said rope, substantiallyas i shown and described.

6. A .boiler-,cleanercoinprising a 4pipe adapted to b e passed through abloW-o valve held on fthe boiler, a valve held at QI' near one end of the said pipe, a rope adapted to be connected with the body ofthe said valve, a drum adapted to wind up or'unwind the said rope, and a frame carrying the said drum and adaptyedf-to be clipped o n the said blow-off valve, .Substantially as shown and described.

7, In a boiler-cleaner, the combination, with a Valve-body and a gate-Valve arranged therein, of .a `pipe extending from the said Valve- .body and provided with a stuffing-box, a dis- A,chargepipe fitted to slide in the said stuffingboX and Vaive-body pipe and adapted to pass ythrough fUheSaid lValve-body, a valve held on the said discharge-pipe, and means, substan- Chmgypipe through the Ysaid -stuf'ng-DOX pipe; and valve-body, ,Subsfllly @s Set fdl-th.
